The Implementation of Inkjet-Printed Filtering Antenna on the Textiles

Inkjet-printed technology is useful for substrate selection. The advantages of inkjet printing technology is fast process, costs less than other additive manufacturing technologies, controlled pattern easy, saving the material up to 90%, and environmentally friendly, which become more attention. The project produces stacked patch antenna on the textile using multilayer inkjet printing technology. The stacked patch can achieve wide bandwidth and high gain. The short-pins obtain a filtering effect due to change the phase of distribution current. These two structures make the filter patch antenna achieve light, thin, and compact size for wearable electronics applications. In the following is our proposed plan for this project: 1. Screen printing on the textile and extract high frequency parameters: screen printing polymer (Fabink-UV-IF) to obtain inkjet printing conditions on the textile and extract high frequency parameters. 2. Inkjet printing SU8 via hole and fill by silver ink: development dielectric via hole and fill by silver ink to obtain device size accuracy. 3. Textile filter antenna design, implement and measured: calculate antenna size by formula and simulate the characteristic by HFSS software. Implement stacked patch antenna by multilayer inkjet printing technology. 4. Textile filter antenna reliability test: bending test and high temperature and high humidity test.
